Fixing possible losing data changes:
1. New flag - BM_JUST_DIRTIED - added for BufferDesc;
2. All data "dirtiers" (WriteBuffer and WriteNoReleaseBuffer)
set this flag (and BM_DIRTY too);
3. All data "flushers" (FlushBuffer, BufferSync and BufferReplace)
turn this flag off just before calling smgr[blind]write/smgrflush
and check this flag after flushing buffer: if it turned ON then
BM_DIRTY will stay ON.
